BCM

bcm(车身控制模块)就是设计功能强大的控制模块,实现离散的控制功能,对众多用电器进行控制。 bcm(车身控制模块)的功能包括:电动门窗控制、中控门锁控制、遥控防盗、灯光系统控制、电动后视镜加热控制、仪表背光调节、电源分配等。 BCM具有以下发展趋势:BCM控制对象更多;各电子设备的功能越来越多,各种功能都需要通过BCM来实现,使得BCM功能更加强大;各电子设备之间的信息共享越来越多,一个信息可同时供许多部件使用,要求BCM的数据通信功能越来越强;单一集中式BCM很难完成越来越庞大的功能,使得总线式、

博通

Broadcom Corporation (博通公司)(Nasdaq:BRCM)是全球领先的有线和无线通信 半导体公司,博通(Broadcom)是有线和无线通信半导体领域的主要技术创新者和全球领先者,在1991 年由 Henry T. Nicholas III 博士和 Henry Samueli 博士创立。Broadcom 产品实现家庭、 办公室和移动环境中的语音、视频、数据和 多媒体传递。博通为计算和 网络设备、数字娱乐和宽带接入产品以及移动设备的制造商提供业界 最广泛的一流片上系统和软件 解决方案。这些解决方案支持博通的核心任务:Connecting everything(连接一切)。   Broadcom 是世界上最大的无生产线半导体公司之一,2006 年收入为 36.7 亿美元, 拥有 2,000多项美国专利和800多项外国专利, 还有6,000项待审批的专利申请,同时拥有最广泛的知识产权组合之一,能够解决语音、视频和数据的有线和无线传输。

BCM5488这个新的65纳米八口CMOS物理层器件采用了Broadcom®  BroadR-ReachTM技术,提高了使用标准以太网电缆的灵活性,可延长10/100以太网信号在单、双或4对5类线以及电话电缆上的传输距离(可延长至500米)。
